not 100% sure but I think the wavelength is 5 and amplitude may be 3
Answer:
Neural: faster and shorter in duration
Endocrine: slower and longer in duration
Explanation:
The nervous system is responsible for transmitting nerve impulses through the molecules that manufacture and secrete neurons, called neurotransmitters. This information is transmitted through the nervous way
The responses of the nervous system are fast, brief and very specific, associated with responses of movement and sensory perception
The endocrine system is characterized because it controls its functions through chemicals called hormones. It is responsible for very diverse functions, associated with metabolism and growth.
These responses tend to be slower than those of the nervous system but of longer duration, since it comprises functions that are regulated slowly.
Invasive species are not native to the new ecosystem that they are invading therefore they have the upper hand. These species have different adaptations that help them spread faster than the other stable organisms in the environment. Once the invasive species starts to spread its almost impossible to stop due to its quick growing and competitive nature
D) Seaweed are multicellular, bacteria are not
